, i 4 l f To all vwhom t may concern i i I.

Be it known that I, Davie Josine, a citi-v zen ci 'the Unlted States, residing at Minney apolis, in the county of Hennepin and State Yoi Minnesota, have-'invented certain new and useful Improvements in Interna-l-Crom-k bustion Engines; and l. do declare chef01-A lowin'g to be a full, clear, and exact descrip tion oi the invention, such as will' enable others skilled in the art to which it apper'V tains to make and use the saine:

My invention which relates to improve ments in internal combustion engines has for its object toprovide -a machine of this class which although being; of comparatively siinple and inexpensive construction will be higgfhly eiiicieut and durable, provision be-- ing` niade whereby all near-sare incased tov allow them to. run in oil, the casings being so constructed as to serve as supports for the entire engine. v

With the 'foregoing general object in view. the invention resides in certain novel fea- 4 tures of construction and` in -unique combinations of parts to be hereinafter fully de Ascribed land claimed, the descriptive matter being suppleinentedby the accompanying drawings which constitute. apart of this a'pplication and'in which i .Fwure 1 is a-horlzontal sectional 'view n partly ni elevatlonpligs. 2, d, -l ari-dn are lonfitudlnal sectional'vlews as seen on the ry y planes represented by the lines 2 2,

Extending laterally in -horizontal direc- ,beingr in the forni of a solid imperforate tions from theupp'er corners of the casing 1. is zv pair of cylindrical crank-cases 9, one end of vsaid cases being' closedfand 'enlarged as shown at 10 andinserted snugly into the. awnings 5 andthe rounded corners 3, the enlargements 10 being secured in place by machine screws 1l passing through the upwardly converging edge walls of the casing y 1 and through the top of said casing.

'The other ends of thecrank .cases 9 are closed as seen at i2, said ends being secured hy'screws or the like 13 to the upright innert;

side 1J: of an additional upright flat casing 15, this easing being. preferably ofrectangu-I I y rlar formation elongated horizontally." As clearly shown 1n Figs. 5 and 6, the casing 15 is of lessheight than the casing 1 and is. provided at its Center with a singleleg 16j adapted-to rest on the looror other sup ort' eo 4 j usedfor the engine.l The outer side-1 of the casing 15 isvsecured rexnovablyin place'-` by screws 18 whereby it may be detached -at will.

Both 4crankfcases 9 are formed ofnupper if f and lower vsexni-cylindrical sections' secured l together-not only by the v'means'descrbed at the ends ot'said eases, but byupright screws or the "like 19 ,extendingA through -bosses 20 castintegrally with the aforesaid sections and extending laterally.;thereilrom.A Interposed between'the 4two casings 1 and l51is a horizontalcylinder 21 whose ends .c

areiianged and secured by screws or the like 22'to the inner adjacentportions ofthe cases 9, such' portions being `formed with bosses 23 for-thisjpurpose. The center of the cylinderv 21 is equipped with anyipre-v ferred type ofyalve casing 24 in Wlgichi'n'-v take and exhaust valves 25 andr 26 are positioned, the Sterns 25 and. 26 of said valves as shown clearly in Figs. 3 rand These 11e depending-below the casing and the cylinder.

v tends into the casing 1, spiral gears'32 being keyed thereon and disposedin said casing, these gears being meshed with a' larger spiral gear 33 also positioned in the casing 1 and secured to a powershaft 34 which passes transverselyfthrough both casings 1 and 15 below the cylinder' 21. Since theV improved engine is of the four-cycle type and since the valves 25 and 26 are operated directly'from the power shaft 34, itis essential that the latter travel aty one half the speed of the crank shafts 30. This end is attained by the proper ratio between gears 32 and 33.

The upright horizontally spaced stems 25* and 26* of the intake and exhaust valves 25 and 26 respectively, are rovided withy rigid arms 35 projecting horizontally from the lower ends of said stems into parallel `relation, said arms being received between "guide fingers 36 carried on a rigid arm 37 projecting horizontally from a longitudinally disposed bar 38 secured'at its ends to the lower sides of the bosses 23. Thus, the arms 35 will rbe guided in4 their vertical movement, such movementv being imparted thereto by appropriate cams 39 secured on the power shaft 34.

One of the crank shafts'30 projects into the casing 15 and is4 provided with agear 40 meshing with an intermediate idle ar 4.1 which in turn meshewwith' a ar 42 secured on the end off a transvers'e orizontal magneto and timer shaft 43, the three f gears 40, 41 and 42 being disposed in the aforesaid casing 15. As clearly shown in several of the figures of the drawings, the shaft 43 is positioned in a plane above the cylinder' 21. This locationy is preferable though not essential, it being obvious that any preferred t pe of timer may be operated by said s aft and that if desired, a magneto may be driven thereby.

In operation, as the two pistons .7 first recede from each other,` the intake valve 25 will be opened, thus `causing suchy pistons to draw a charge of explosive mixture from the carburetor C into the cylinder 2l. This having been done, the pistons 27 travel. toward each other to compress the charge of mixture, and when said pistons assume the relation shown in Fig. 2. by an appropriate spark plug I disposed centrally )etwcen the ends of the cylinder. It is to be observed that when this occurs,

l under. power,

continually lubricating the ignition is effectedbeing'raised past a medial line while the other is lowered beyond'such line. Thus, when expansion within the cylinder takes place, it will act in such a manner on both pistons. as to rotate the crank shafts 29 the two shafts traveling in synchriia due to the single gear 33 meshi e gears 32 which are secured to the ends of said shafts. By the time the power stroke of the engine is completed and the pistons again travel toward each other, the exhaust valve 26 has been o ned by its cam and scavenging of the cy inder takes place, thereby ilacng it in readine for-the reception o a new charge when the plstons a hin recede from each other.

AFrom the oregoing, the construction and manner of operation `of the improved machine will be readily understood and it will be obvious that the machine incorporates a number of improved features. Amo the most; important of these is the fact that the two casings 1 and V15 not only serve assupports for the entire engine, but as housings for the gears confined therein. The casing 1 may well be partially ld with oil, th'us gear 33 which will in turn lubricate the gears 32. i

In conclusion, I will state that although numerous details kof construction have been shown and described for illustrativey purposes, numerous changes may be made within the. scope of the invention as claimed without sacrificing the primary advantages thereof.
